Neolithic builders had an understanding of science

The Neolithic farmers and herders who built a massive stone chamber in southern Spain nearly 6,000 years ago seem to have possessed a good rudimentary grasp of physics, geometry, geology and architectural principles. Using data from a high-resolution laser scan, as well as unpublished photos and diagrams from earlier excavations, archæologists pieced together a probable construction process for the monument known as the Dolmen of Menga.
